The aim of this study was to determine the fatty acid compositions of mud snail,
Cerithidea obtusa. Bligh and Dyer method was used to extract oils/fats from Cerithidea
obtusa. The lipids were extracted separately into two batches based on the weight of
Cerithidea obtusa that are 1.12 ± 0.01 g and 20.63 ± 0.09 g. The lipid content of
Cerithidea obtusa were 31.54 ± 2.6 % in the first batch and 17.15 ± 1.7 % in the
second batch. The extracted oils/fats were converted into fatty acid methyl ester and
its composition was analyzed by using gas chromatography with flame ionization
detector (GC-FID). It was found that fatty acid compositions in Cerithidea obtusa
showed highest amount of saturated fatty acids (SFA) (87.06 ± 0.17 % for first batch
and 57.24 ± 0.42 % for second batch) followed by polyunsaturated fatty acids (PUFA)
(9.35 ± 0.13 % for first batch and 26.51 ± 0.41 % for second batch).
